Description:

Abstract:

The United States Geological Survey (USGS) is conducting a study on the effects of climate change on ocean acidification within the Gulf of Mexico; dealing specifically with the effect of ocean acidification on marine organisms and habitats. To investigate this, the USGS participated in cruises in the West Florida Shelf and northern Gulf of Mexico regions aboard the R/V Weatherbird II, a ship of opportunity lead by Dr. Kendra Daly, of the University of South Florida (USF). This cruise occurred May 03 - 09, 2011, leaving from and returned to Saint Petersburg, Florida. The USGS collected data pertaining to pH, dissolved inorganic carbon (DIC), and total alkalinity in discrete samples. Thirty-four underway discrete samples were collected approximately hourly over a span of 1632 kilometer (km) track line, additionally 44 discrete samples were taken at four stations, these were taken at various depths. Flow-through conductivity-temperature-depth (CTD) data were collected, which includes temperature, salinity, and pH. Corroborating the USGS data are the vertical CTD profiles collected by USF, using the following sensors: CTD, oxygen, chlorophyll fluorescence, optical backscatter, and transmissometer. Additionally, discrete depth samples for nutrients, chlorophyll, and particulate organic carbon/nitrogen were collected.

Purpose:

The purpose is to study the effects of climate change on ocean acidification within the Gulf of Mexico.

Supplemental_Information:

The USGS Saint Petersburg Coastal and Marine Science Center (SPCMSC) - St. Petersburg, FL, assigns a unique identifier to each cruise or field activity. For example, 11BHM01 tells us the data were collected in 2011 for Benthic Habitat Mapping and the data were collected during the first field activity for that project in that calendar year. Refer to http://walrus.wr.usgs.gov/infobank/programs/html/definition/activity.html for a detailed description of the method used to assign the cruise ID.

Data_Quality_Information:

Logical_Consistency_Report:

The QA/QC process looked for internal consistencies in the data by calculating the results using CO2SYS and back checking with the collected data.

Completeness_Report:

These data are collected along tracklines (2-D) and therefore inherently incomplete geologic details between lines must be inferred.

Lineage:

Process_Step:

Process_Description:

Flow-through data was collected using a Sunburst AFT pH, which measures pH on the total hydrogen ion scale, was attached to the flow-through system. This system sampled the seawater approximately every three minutes and has a precision and accuracy of 0.001 and ±0.003, respectively. The Sunburst AFT-CO2 system was used to measure the partial pressure of CO2 in water (pCO2) and was attached to the shipboard flow-through system. The instrument sampled approximately every five minutes and had a precision and accuracy of about 1 ppm and ± 3 ppm, respectively.

Overview_Description:

Entity_and_Attribute_Overview:

All attributes are common between the three data formats provided (.csv, .xls, .shp), except for the attributes FID and SHAPE (indicated by *), which are found only within the shapefile (.shp) because they are unique to that data type. Additionally, the GPS data was taken from the Weatherbird II's navigation logs and was matched with the time logs on the sonde. These data have not been QA/QC yet, and as such could have data errors due to tubes clogging, or flowthrough shutdown for inclement weather.
